This hole saw kit is perfect for cutting holes in sheet metal. Metal hole saw kit includes center drills that prevent the hole saws from walking when starting to cut. Our spot drills have a step structure to reduce the cutting resistance. Made with M35 HSS steel, they will last longer than many other pilot bits on the market. 3 extra pieces are included in this ideal knockout set. OPERATING INSTRUCTIONS Set up the sheet metal hole cutter into the drill. Position the pilot drill bit where the hole must be cut. Make sure that the hole saw is at 90° to the plane where the hole is being cut. Start off slowly and gradually increase the rotation speed. Use gentle, consistent pressure to produce smooth, reamed holes. It is important to control the pressure throughout to avoid premature breaking of the carbide tipped blades. For continuous cutting, do not forget to use plenty of cutting fluid.
